摘要

Based on the dynamic characteristics of marine structures subjected to underwater explosion (UNDEX), this work focuses on the deformation and failure of different stiffened plate of UNDEX. With the Coupled Euler–Lagrange method (CEL), the damage of explosion impact on the fixed stiffened plates is numerically simulated by the finite element software ABAQUS. The damage process of different stiffened plates under near field explosion is analyzed, besides the deformation and failure mode of stiffened plates under explosion impact load and the deformation law of stiffened plates under typical explosion impact load are obtained. The results show that the configuration of the stiffener is a factor which influences the deformation of plate frame. When the total mass of the three kinds of stiffened structures remains unchanged, the protection effect of the well shape stiffener is better. Moreover, the damage characteristics of stiffened plates under different explosion distances are studied, and two different damage modes are obtained.
